Vinca 'Cora Deep Lavender': A Heat-Tolerant Beauty for Vibrant Landscapes

Vinca 'Cora Deep Lavender'

When summer heat turns other annuals crisp, Vinca 'Cora Deep Lavender' hits its stride. This outstanding cultivar from the Cora series delivers rich, deep lavender blooms nonstop from late spring until frost, all while laughing off high temperatures, humidity, and drought. Its glossy, deep-green foliage forms a neat, mounding habit that stays attractive without deadheading—a true workhorse for beds, borders, and containers.

Why Gardeners Love the Cora Series

Bred specifically for disease resistance (especially to aerial Phytophthora, a common vinca killer), the Cora series represents a quantum leap in vinca performance. 'Deep Lavender' showcases the series' hallmark traits: large, overlapping petals that create a full, rounded flower; a compact, well-branched structure; and exceptional heat tolerance. It thrives where other annuals falter, making it a go-to for Southern gardens and any spot that bakes in afternoon sun.

Growing Conditions

• Light: Full sun to partial shade. Best flowering occurs with at least 6 hours of direct sun.
• Height: 12–18 inches tall, forming a tidy mound.
• Spread: 12–18 inches wide.
• Soil: Well-drained, average fertility. Tolerates poor, sandy soils.
• Water: Low to moderate once established. Drought-tolerant; avoid overwatering.

Landscape Uses

Plant in mass for a carpet of color, edge a sunny walkway, or tuck into mixed containers where its upright habit plays well with trailing companions like sweet potato vine or calibrachoa. It also excels in window boxes and hanging baskets. Deer and rabbits typically leave it alone.

Care Tips

No deadheading needed—spent flowers drop cleanly. Apply a slow-release fertilizer at planting, or feed monthly with a balanced water-soluble formula. Ensure good air circulation to prevent fungal issues. In humid climates, avoid overhead watering.
